VEH ICLE-SEAT.

SPECIFICATION forming part of Letters Patent No. 254,115, dated February 28, 1882.

Application filed September 30, 1881.

To all whom it may concern:

Be it known that I, FRANK A. GOMsTOcK, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a. new and useful Improvement in Vehicle-Seatacks, of which the following is a specification.

My invention relates more particularly to scat-backs made of metal; and the novelty consists in making them in sheet-metal sections having their proximate edges turnedback toward the body of the sections, and in uniting the sections thus formed by means of strong strengthening corner-pieces adapted toreceive the turned-back edges of the sections, whereby astron ger seat-back is obtained, which is cheaper, on account of the less waste of material in making it, over those which are made of a single piece bent into shape.V

In the accompanying drawings, Figure lis a perspective view of avehiele-seat back made in three pieces or sections, the sides being attached to the back and firmly held. by my lockl ing device, which in this instance is applied on the inside of the backs sections at their points Of connection or angles. Fig. 2 is a rear view of a back, showing the locking device applied on the outside at point ofconnection. Fig 3 is an enlarged detail view, showing part of the seatback and side with their vertical edges turned back, over which a piece of metal made to embrace the turned edges is placed and fastened in any suitable manner, thus forming a dovetailing slide, and locking or firmly holding the parts together. Fig. 4 is an enlarged detail/view, showing the fastening applied to the inside of the back. Fig. 5 is a similar view with the fastening on the outside.

A is the rear of the seat-back, and B and C' are the sides.

a, b, ando are the ordinary flanges to which the seat-bottom is attached.

(No model.)

a', b', and c are the ordinary top tlanges to the back and sides of vehicle-seats,for strengthening and finishing purposes.

A and B are the turned edges or flanges of the seat-back and sides. These tlan ges are turned back in opposite directions'to each other, and are embraced by the metal dovetaling piece D or'E. This piece D or E is made 5o with its vertical'edges turned inwardly in opposite directions, and it is preferably angular in cross-section, so that its interior will corre-v spond with anges A and B, and by sliding it over these flanges a snug lit will be secured 55 and the parts held firmly together.

It will be observed that it is immaterial whether the attachment be madeon the inside or outside of the back. The same firmness is secured in both cases, and itis onl y a matter of 6o individual preference which Inode is adopted.

The cornersof the seat-back and dovetailed slide may be subjected to a die, by which the flanges are pressed flat and close, forming a smooth clean corner, the metal used being 65 much thinner than indicated by the drawings.

By my invention I am enabled to manufacture seat-backs with much less waste of mate-n rial than by the methods heretofore in use, and

it is apparent that the facilities for repairs are 7o also rendered greater.

Having thus described my invention, what I claim is- Avehicle-seat back composed ot'sheet-metalsections having their proximate edges turned 7 5 back toward the body of the sections, and strong strengtheningcorners having grooves for the reception of the turned-back edges of the sections, and operatin g to hold the sections firmly together, substantiallyas described.
